PSR-PC40 SIL coupling relay Data sheet 106256_en_03 1 © PHOENIX CONTACT 2015-07-14 Description Intended Use The PSR-PC40 SIL coupling relay can be used for power adaptation and electrical isolation in high and low-demand applications up to SIL 3 according to IEC 61508 as well as EN 61511. Using this module, circuits are interrupted in a safety-oriented manner. The safety relay is equipped with two enabling current paths that drop out without delay corresponding to stop category 0 according to EN 60204-1. The module performs a selftest the moment it is switched on and prevents the enable contacts from being closed in the event of an error. Features – – – – By filtering the controller test pulses, premature failure of the safety relays is prevented. If an error occurs inside the module, the internal device input impedance is affected. As such with compatible, safe systems, the test pulses sent from the controller may be disrupted and the error can be reported back to the corresponding digital output without any additional wiring effort. – – – – – – – SIL 3 coupling relay for safety-related switching off Can be used in high and low-demand applications Approved for Class I, Zone 2 applications Easy proof test:    - Active error acknowledgment via A1    - Self-monitoring, with device-internal locking    - Visually on the device Integrated DCS test pulse filter Low inrush current 2 undelayed enabling current paths 1 digital signal output Option of screw or spring-cage terminal blocks for plugin 12.5 mm housing width Controller-specific Termination Carrier available on request WARNING: Risk of electric shock Observe the safety instructions in the corresponding section!
